This easy, 3-topping burger made with mozzarella, avocado, and tomato is the perfect fun change-up for family cookouts when you don't want to serve anything too heavy or complicated.
Prep - Slice the mozzarella, slice the vine tomato, and mash the avocado – set aside.
Grill - Grill the burger patties to your preferred doneness (use a meat thermometer to check the temperature! Cooking by temperature is much more accurate than cooking by time). Top with mozzarella after flipping the burger patty since mozzarella takes a couple minutes longer than a thin slice of American or cheddar cheese to melt.
Assemble - Spread the mashed avocado on the bottom halves of the burger buns, then put cooked patties on top. Finally top each burger with a slice of tomato.
Serve - Enjoy with your favorite side and a cold beer!
Notes
Melting the mozzarella: Since fresh mozzarella comes in thick slices, get it on the patty earlier than you normally would for a regular cheese burger. Since we normally cook on a cast iron grill pan, I put the mozzarella on as soon as I flip the burgers. When grilling, I don’t need to do it that early, but I give it about 2 or 3 minutes longer than I would for classic burger cheeses like American or cheddar. Messy avocado: While the presentation of sliced avocado might look nicer than mashed avocado, it makes for a much messier burger (not that we’re any strangers to messy burgers!) We recommend instead mashing the avocado and putting it on the bottom bun under the patties for the easiest and cleanest meal. Enhance the avocado: If you want the avocado to stand out a little more, make what we call “fake guac”. When mashing the avocado simply add a little salt and lime juice. The salt and acid wil both brighten and enhance the flavor of the avocado for the perfect burger topping!Fresh ingredients: With all the toppings being fresh ingredients, it’s important to make sure they’re high quality and ripe. Pick out your favorite mozzarella, a bright red, juicy tomato, and a soft, dark green avocado.
